Answer:
P(t) = 200·0.95^t
Step-by-step explanation:
Each year, the population drops to 95% of its previous value. That is, the population is multiplied by 0.95 each year. Repeated multiplication is signified by an exponent. Here, that exponent is the number of years from today (t).
The population function can be written as ...
P(t) = 200·0.95^t
Answer:
$31
Step-by-step explanation:
(99 - 6) / 3
Answer:
2/35
Step-by-step explanation:
The only way we can solve this problem is to assume that the given complement of pieces is of a full kit before one went missing. The total number of pieces in the kit is ...
... 9 + 8 + 12 + 6 = 35
Of those, 2 are red with four holes. Thus the probability that a randomly chosen piece is red with 4 holes is 2 out of 35, or 2/35.
____
If this is the kit contents after the piece went missing, we have no way of knowing the color or hole count of the missing piece. If the kit is supposed to contain 13 blue pieces, for example, then the probability is zero that the missing piece is red.
You are given the perimeter of the desk which is 54 inches. Also, you are given the length of the disk with a value of 15 inches. You are required to solve for its width. The top of a desk is assumed to be rectangular since the problem asks for its width. The equation of the perimeter of a rectangle is P=2L+2W. Let us designate the values for P=54 inches and L=15 inches. Plugging in the values to the equation;
P=2L+2W
54 inches = 2(15 inches) + 2W
54 = 30+2W
54-30 = 2W
2W = 24
W=24/2
W= 12 inches
Therefore, the width of the top desk is 12 inches.<span>
